What Is a Rainscreen?

Architectural Rainscreen Systems Overview

As the name suggests, a rainscreen is akin to a raincoat. It protects the building from the elements: rain, snow, and ice. If an elegant cladding material such as decorative glass is used, a rainscreen can also deliver an added dose of modernity and style. It can be easily attached to the structural walls or floor slabs of a new or old building, creating a protective envelope around it.

Architectural Rainscreen Defined

A rainscreen is an exterior over-cladding system that stands off from the building’s outer walls, protecting them against water infiltration. It reduces the damaging effects of wind-driven rain and moisture, including structural deterioration, as well as mold and mildew growth. In simple terms, a rainscreen is akin to a stylish raincoat that shields the building from the elements.
